Digital Display for Signal Input DSA 9648 

The digital display for signal-input DSA 9648 for panel-installation has been designed for standard signals 0/4…20 mA or 0…+10 V DC. The device offers an integrated transmitter supply for direct connection of 2- an 3 wire transmitters for e.g. pressure or temperature. The connection of potentiometers is possible as well. Indicating range and decimal point are free programmable in the range of ± 99990 (fixed zero selected).


  • For standard signals 0/4…20 mA or 0…10 V
  • Indicating range and decimal point free programmable
  • Optional with max. 4 outputs, spdt relays or transistor
  • Led-display, 14,2 mm
  • Display range ± 9999(0) digits
